TOP-ROLL CLEARER FOR SPINNING-FRAMES.

Specification of Letters Patent.

Patented Jan. 29, 1907.

Application filed October 20, 1906- Serial No. 339.776.

To all whom it TIl/GLZ/ concern:

.Be it known that 1, JOHN T. MEATS, a citizen of the United States, anda resident of Taunton, county of Bristol, State of Massachusetts, haveinvented an Improvement in Top-Roll Clearers for Spinning-Frames, ofwhich the following description, in connection with the accompanyingdrawings, is a specification, like letters on the drawings representinglike parts. This invention has for its object the production of novelmeans for supporting the top roll clearer of a spinning-frame and alsofor relieving the top rolls of a part of the Wei ht of the clearer.

T e top-roll clearer is of the type shown in United States Patent No.825,584, granted July 10, 1906,-to Chandler, a flat web or band or aplurality of such bandsof'textile material being held at front and rearin a cover which is mounted on the frame, the textile material restingon the top rolls and removin lint, &c., therefrom.

in the patent referred to the clearer is pivotally mounted on thecap-bar; but in practice I have found it important that the clearershould maintain a constant position with relation to the front top roll.

As will be understood by those skilled in the art, the journals of themiddle andback top rolls are guided and controlled as to their positionby the cap-bar, and the front top roll is guided by cap-bar slides,which are adjustably mounted on the cap-bar. This construction inemployed because fordiflerent lengths of staple in the fiber to be spunthe middle and back rolls are moved toward or away from the front roll,and when the toproll clearer is mounted on the cap-bar, as has beencustomary heretofore, any change in the position of the middle and backrolls causes a change in the position .of the top-roll clearer withrelation to the front roll. To obviate this variable relation betweenthe top-roll clearer and the front roll, I have herein so mounted theclearer that its position is unchanged relatively to the front rollentirely irrespective of the changes which may be made in the distancebetween the front roll and the middle and back rolls. So, too,

in spinning very fine yarn it is sometimes very desirable to have aslittle weight as possible on the top rolls, and I have herein providedmeans for supporting the top-roll clearer in such a way that the toprolls are relieved of a portion of its weight.

slides detached. Fig. 4 is a top plan view thereof.

The pedestal A, having'a fixed bearing for the front lower roll L, themiddle and back lower rolls L L, supported in bearings on the head orcap A, movably mounted on the top of the pedestal, and the top rolls T TT may be and are all of well-known construction.

' The usual journals of the middle and back top rolls T T rest in theusual guides or sockets 1 1, formed in the'endfingers 2 of the cap-bar,Fig. 2, the neck portion 3 of each finger inthe present embodiment of myinvention being reduced in thickness to leave an externalclearance-space 4, Fig. 2, for a purposeto be described.

As shown in Fig. 1, the cap-bar is pivotally connected at 5 with thehead or cap A, as usual, so that any movement of the head to vary thedistance between the roll L and rolls L L willeifect a correspondingchange betweenthe roll T and rolls T T.

Such change is .made for different lengths of staple in the fiber to bespun, as will be manifest to those skilled in the art, and in Fi 1 twopositions of the middle and back rol s are shown in full anddottedlines, 'respectively.

T hejournals of the front top roll Trest in guides or sockets 6 in thecap-bar slides, one of the slides being shown at 6, Figs. 1, 3, and 4.Said slides are shown as provided with elongated lon itudinal slots' 7,through each of which a c amping-bolt 8 is passed into a hole 9, Fig. 2,in the adjacent finger of the cap-bar, so that the roll T can bemaintained in pro er cooperative relation with the lower roll J.

The top-roll clearer (see Fig. 1) is of the type shown in the Chandleratent referred to, the textile web or band being supported at front. andrear on the downturned portions of the cover W the textile material &c.therefrom.

In order that the clearer shall maintain a constant position withrelation to the front transverse hub 0r bearing 11, the ear passing upthrough the clearance 4 of the cap-bar end finger, with the hub wellabove the neck 3 of the cap-bar. The two hubs 11 are thus alined atopposite ends of the cap-bar, and the pintles 12 of the top-roll clearerare pivotally mounted in the hubs, so that the clearer is made topartake of any change in the adjustment of the cap-bar slides. Hence therelative position of the clearer and the front roll T remains constant,which is very important, in order that the clearer may properly performits work. I also provide a positive closed pivotal connection or fulcrumfor the top-roll clearer, a safer construction than the open-slotstructure used in the Chandler structure.

In spinning very fine yarn it is sometimes desirable to have as littleweight as possible on the top rolls, and to take off from such rolls adesirable portion of the weight of the clearer I have formed an uprightlug or projection 13 on the outer end of each cap-bar slide to supportthe front or outer end of the clearer, as shown in Fig. 1. By this meansthe weight of the clearer-cover WV is altogether taken off the toprolls, the tightness of the web or band W determining the pressure orfrictional action upon the top rolls. My invention is not restricted tothe precise construction and arrangement herein shown and described, asthe same may be modified or varied in different details by those skilledin the art without departing from the spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a spinning-frame, a cap-bar, middle and back top rolls guidedthereby, the front top roll adjustably connected with the capbar, and ahinged top-roll clearer mounted to maintain a constant position relativeto the front top roll.

2. In a spinning-frame, top rolls, means to vary the distance betweenthe middle and back rolls and the front roll, and a hinged toprollclearer mounted to maintain a constant position relative to the frontroll irrespective of the distance between it and the middle and backrolls.

3. In a spinning-frame, top rolls, a ca bar in which the middle and backtop r01 s are guided, guides for the front top roll adjustable on thecap-bar, and a hinged top-roll clearer adjustable simultaneously withsaid guides.

4. In a spinning-frame, top rolls, means to vary the distance betweenthe middle and back rolls and the front roll, and a top-roll clearerpivotally mounted on said means.

5. The combination, with a cap-bar and middle and back top rollscontrolled as to their position thereby, a front top roll, and slidesadjustable on the cap-bar to control said roll, of a top-roll clearerpivotally mounted on the slides.

6. The combination, with middle and back top rolls, and a cap-bar bywhich they are controlled, of a front top roll, guiding means thereforadjustably mounted on the capbar, and a top-roll clearer pivotallymounted on said means.

7. The combination, with middle and back top rolls, and a cap-bar bywhich they are controlled, of a front top roll, guiding means thereforadjustably mounted on the cap-bar, a top-roll clearer pivotallyIHOUl'llJGd at its rear end on said means, and a support on said meansfor the front end of the clearer, to relieve the top rolls of a portionof the weight of the clearer.

8. In a spinning-frame, a cap-bar, middle and back top rolls guidedthereby, longitudinally-adjustable slides mounted on the capbar, eachslide having its rear end upturned outside the cap-bar and provided witha bearing, a front top roll guided by the slides, and a top-roll clearerhaving pintles pivotally mounted in the bearings on the slides.

9. In a spinning-frame, a cap-bar, middle and back top rolls guidedthereby, front toproll guide members longitudinally adjustable on thecap-bar and upturned at their rear ends above the cap-bar, and atop-roll clearer fulcrumed on the upturned portions of said members.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
